There were major delays on the Milwaukee West and Milwaukee North lines Wednesday due to earlier switching problems. Wednesday night's delays lasted up to an hour for many Metra riders, who are now concerned about what's in store for the Thursday morning commute.

Trains were backed up during the Wednesday evening rush hour and there was some passenger confusion on which trains are going to what destination.

Metra expects to have a normal commute on Thursday, but Metra passengers are weary after facing weather delays for three days in a row. Thanks to the weather, Metra passengers were - once again - delayed during rush hour on Wednesday.

"I've been here for almost an hour now, unfortunately," said Becky Kelley, delayed Metra passenger.

Frustrated passengers on the Milwaukee North & West lines packed Union Station.

"I got homework to do; I got things to do and I don't have my laptop with me. If I had known, I would have stayed at school and done my work," said Amal Simm, delayed Metra passenger.

Outside, the switch heaters were fired up, but Metra officials said the cold weather triggered switching problems that created a Metra mess around 5 p.m. and made folks wonder when they'd get home.
